Water storage tank

stormwaterload resistorpolyethylene (PE)

Compression-resistant storage tanks 4.5 m³ or 5.5 m³ storage volume Manufactured without seams Large access shaft DN 100 tube bushings with seals Non-slip cover, vehicle-duty capacity STABLE AND LEAK-TIGHT - GUARANTEED! The WISY storage tank is optimally shaped to withstand vertical compressive loads. The rainwater storage tank is a seamless one-piece unit for long-term leak-tightness. We offer a 20-year guarantee on the durability of the environmentally friendly polyethylene tank material. Thanks to their exceptional strength, WISY storage tanks are capable of withstanding the weight of passing road vehicles. This means that they can be installed under the driveway as well as in the garden. Even when weather conditions are wet, the non-slip cover is safe to walk over. EASY TO HANDLE ON SITE Thanks to their light weight and two rugged lifting eyes, WISY storage tanks are particularly easy to handle on site (using a mini-digger, for example). When the excavated pit is filled up with gravel the storage tank is fully supported from below. Tube bushings with fitted seals make installation even easier. For additional safety, a compressed water equalizing valve is fitted in the tank base for protection in the event of groundwater collection around the tank. The wide access shaft ensures ease of entry for maintenance work.
